I have a 4.0 Blade that I'll be handing down to my son so I thought I'd try to get a little larger one for myself. I'm considering the Blade 4.9, but am also considering the radsail 5.0. I've never flown the radsail and don't really have opportunity to try them out, but I've read that it might be better for buggying and I've discovered that it's much less expensive. Any advice or reasons that I should stick with the Blade and spend the extra money?

I'm assuming you are in Europe or UK. If someone recommended a Radsail over a Blade, I can only assume it is because the Radsail is a lower lift kite and not as violent as Blade IV. If you are looking for a good buggy engine, consider the Blurr, Rage, or Peter Lynn Reactor. All of them develop smooth power down in the window where you want it.

The blade is tamed quite a bit on the low lift setting but I've had the handles ripped right out of my hands before I even knew the gust hit me even in the low lift setting. However in more suitable winds, Wexler could fly it at ease. I even noted once that I was more comfortable with Wexler flying the blade 6.5 on low lift than the original Crossfire I 5m. The Blade was less snatchy.
